We can imagine our universe made of different objects like sun, earth, moon etc. Similarly we can imagine our car made of different objects like wheel, steering, gear etc. Same way there is object oriented programming concepts which assume everything as an object and implement a software using different objects. You can think of a class as a template for making many instances of the same kind or class of object. You define a class once and then make many objects that belong to it.
The three basic components of object orientation are; Object oriented analysis — functionality of the system Object oriented designing — architecture of the system Object oriented programming — implementation of the application Object Oriented Programming Principles The three major principles of OOP are; Encapsulation — this is concerned with hiding the implementation details and only exposing the methods. The main purpose of encapsulation is to; Reduce software development complexity — by hiding the implementation details and only exposing the operations, using a class becomes easy. Protect the internal state of an object — access to the class variables is via methods such as get and set, this makes the class flexible and easy to maintain. The internal implementation of the class can be changed without worrying about breaking the code that uses the class. Inheritance — this is concerned with the relationship between classes. The relationship takes the form of a parent and child.
Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the model represents the information the data of the application; the view corresponds to elements of the user interface such as text, checkbox items, and so forth; and the controller manages the communication of data and the business rules used to manipulate the data to and from the model. Model handles all our database logic. Using the model we connect to our database and provide an abstraction layer. Controller represents all our business logic i. View represents our presentation logic i.
The Model-View-Controller (MVC) Design Pattern for PHP
As of 10th April the software discussed in this article can be downloaded from www. I am no stranger to software development having been a software engineer for over 25 years. I have developed in a variety of 2nd, 3rd and 4th generation languages on a mixture of mainframes, mini- and micro-computers which are now called Personal Computers. I have worked with flat files, indexed files, hierarchical databases, network databases and relational databases. I have written code which has been procedural, model-driven, event-driven, component-based and object oriented.
It is equivalent to an intensive coding bootcamp for one month where intermediate PHP developers could enhance their coding skill by following a few rules. This book will give you enough PHP code to practice, so that you can master the language implementing the OOP concepts. All you need to do is code everyday from eight to twelve hours using this guide. After one month, you will find, object oriented programming is much easier than before. You want to be a good PHP web developer; but you have been stuck in the crack of object oriented programming concepts.
At first glance, the code behind a symfony-driven application can seem quite daunting. You'll also see references to classes that are otherwise nowhere to be found within the application folder, and the directory depth stretches to six levels. But once you understand the reason behind all of this seeming complexity, you'll suddenly feel like it's so natural that you wouldn't trade the symfony application structure for any other. This chapter explains away that intimidated feeling. Symfony is based on the classic web design pattern known as the MVC architecture, which consists of three levels:.
Learn Object Oriented Programming, the PHP Language, and the Model-View-Controller Design Pattern.
Танкадо использовал наживку для дурачков… и АНБ ее проглотило. Сверху раздался душераздирающий крик Стратмора. ГЛАВА 86 Когда Сьюзан, едва переводя дыхание, появилась в дверях кабинета коммандера, тот сидел за своим столом, сгорбившись и низко опустив голову, и в свете монитора она увидела капельки пота у него на лбу.
Поднявшись по ступенькам, она обнаружила, что дверь в кабинет шефа открыта, поскольку электронный замок без электропитания бесполезен.
